I broke in my new bong last night, it's a cheap piece of plastic and the water seal isn't even water-tight so I get a little leakage...but holy shit. It's incredibly tall and the shotgun is small and surrounded by rubber so that even after you're done, the smoke remains in the chimney. I manage to get a lung-full of smoke out of it about 10 minutes after I lit up.
I'm definitely not big on smoking/ getting high, and I can't stand weed-culture, but with that being said I feel relaxed and calm this morning and my missus--who has clinical anxiety and depression--also reports feeling much more chill.
